What do I do? Will we work it out?

Me and my ex were together for 4 years. I havent saw him in 6 weeks and we broke up 4 weeks ago due to him going through some things and feeling depressed and he wanted to be on his own for a while whilst he dealt with this. He told me its just for now and he loves me and is so happy we got together and were going good. However since breaking up weve spoke maybe 3 times. Its a very short, blunt conversation and he doesnt want to open up. He keeps saying he wants space and he doesnt know if he wants a relationship whilst hes dealing with this situation. Its been hard but Ive gave him his space and have had advice from other people that he will contact soon as Ive respected his choice for space. I just want some advice on how I can make him realise we can fix things together and work on our relationship together. I love him with all my heart and Id do anything to make this work. How can I help the communication and relationship when he needs space????

All of my things are still at his house and Ive asked him twice if I can collect them. He told me hed let me know when hes got a day off work. However since then hes had 4 days off. Is he keeping them there because he isnt 100% sure hes making the right decision? There have been plenty of opportunities for me to collect. So I am confused.
